Article Introduction：The writing method of model.php for PHP querying the Mysql database is not perfect enough. In each method, you need to declare the $con object of mysql yourself and close the $con object of mysql yourself. In this way, if there are too many query methods, a lot of code for declaring $con objects and closing $con objects will be added for no reason. In fact, you can completely use PHP's constructor and destructor to inject $con objects into each query method of the database class, and at the same time automatically recycle the $con object after each query.

Article Introduction：Overview of the Math library The math library is a built-in mathematical function library provided by Python. Because complex number types are often used in scientific calculations and not in general calculations, the math library does not support complex number types and only supports integer and floating point number operations. The math library provides a total of 4 mathematical constants and 44 functions. The 44 functions are divided into 4 categories, including 16 numerical representation functions, 8 power logarithmic functions, 16 trigonometric logarithmic functions and 4 advanced special functions. There are a large number of functions in the math library. During the learning process, we only need to understand the function functions one by one and remember some commonly used functions. In actual programming, if you need to use the math library, you can check the math library quick reference at any time. The functions in the math library cannot be used directly and need to be first
